So, I have been following some advice from a local pool shop, not sure if I am on the right track.
We opened up the pool, it had been sitting pretty open for about 2 years. We started by scooping all the murk, leaves, and debris out of the bottom, and we are confident that it is mostly or all out. So all we have left is murky green water.
We had our equipment services and verified it is all working well (1 HP pool pump and sand filter)
At the advice of the pool shop, what we did was started with two 25 gallon buckets of granulated chlorine, dumped half a bucket in with pump running and did this over a span of about a week with the pump running.
I havent really noticed any change at all in the color of the water or clarity. Yesterday I went back by there, and got some "dropoff", diluted it in water and spread out in pool.
Also got some test strips, the chlorine is dark purple (off the charts as expected I guess), my alk was bright yellow (at the lowest end of the spectrum), and the pH wasnt even a choice, it seemed to knock most of the color off with brownish/purple splotchs.
mY next steps is to put the filter on "vaccum to waste" for a while, while refilling the pool from hoses. Later add more chlorine. Does it seem like I am on the right track or are these guys leading me astray?
